Embodiment Construction

[0017] A kind of horizontal fin-tube shell-and-tube heat exchanger described in the embodiment of the present invention, such as figure 1 . The cylinder body 15 forms a closed space with the left tube plate 3 and the right tube plate 8, which becomes the shell side. The shell side inlet pipe 7 is arranged on the right side of the cylinder body 15 close to the tube plate position, and the shell side inlet pipe 7 on the left side of the cylinder body The shell side outlet pipe 16 is arranged at the symmetrical position. The heat exchange tube core is fastened by the heat exchange tube 14 parallel to the axis of the cylinder and the sleeve 13 perpendicular to the heat exchange tube through expansion joints to reduce contact thermal resistance and enhance heat transfer. The fins 13 are stamped and formed to form an expanded heat exchange surface on the outer surface of the heat exchange tube, and the expansion rate exceeds 20, which can greatly increase the heat transfer coeffici...

Abstract

The invention provides a horizontal-fin shell and tube heat exchanger. The horizontal-fin shell and tube heat exchanger comprises a barrel (15), a liquid inlet (1), a left tube box (2), a left tube plate (3), a right tube plate (8), a right tube box (9), a liquid outlet (10) and heat exchange tube cores. The horizontal-fin shell and tube heat exchanger is characterized by further comprising a flow equalizing plate (5) which enables gas to be uniformly distributed on the same. Gas flows on the shell side is uniformly distributed, an impingement baffle (6) is correspondingly arranged at an inlet of a shell-side inlet tube (7), and impact from the shell-side gas flow to a heat exchange tube bundle is reduced. The horizontal-fin shell and tube heat exchanger is particularly applicable to heat exchange processes between gas such as middle-and-high-pressure gas, toxic gas or combustible gas and liquid or phase-change heat exchange processes. A manner of finned tube strengthened shell-side heat exchange is adopted to realize basic balance of heat exchange between the outsides and the inner sides of the tubes, and heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to a high-efficiency horizontal shell-and-tube heat exchanger, which is especially suitable for medium-high pressure, poisonous, combustible gas and liquid or phase conversion heat process. Background technique [0002] Finned tube heat exchangers are widely used in gas-liquid heat exchange or gas-phase heat exchange, and are widely used in air conditioning, electronic device cooling, refrigeration, aerospace and other fields. The fins of this finned tube mainly include integral fins, expansion joint fins and wound joint fins. The integral fins have small contact thermal resistance and high fin efficiency, while the expansion joint fins The expansion rate is high, the contact thermal resistance is large, and the wound fins are in between. Therefore, expansion joint fins are more suitable for gas and liquid with small heat transfer heat capacity difference or phase conversion heat process. sheet heat exchanger. With the continuo...
